Value Collection 706474PR Set Screw 3/8-16 X 1 in Half Dog Point

Product Description

The VALUE COLLECTION 706474PR is a half dog point set screw designed for mechanical assemblies where a protruding locating point is needed to engage a mating hole or slot without fully passing through the workpiece. Manufactured from austenitic grade A2 stainless steel, this fastener provides solid corrosion resistance in wet, chemical, or outdoor service environments. It features a 3/8-16 UNC thread at 1 inch overall length and is driven by a 3/16 inch hex key. Machinists, millwrights, and maintenance technicians install this type of screw in shaft collars, pulleys, gears, and similar mechanical components requiring precise axial or rotational positioning.

The half dog point geometry creates a short, flat-tipped cylindrical extension that seats into a drilled locating hole on a shaft or mating part, making it well suited for applications that require repeatable positioning or where the set screw must resist both axial and radial loads simultaneously. Common installation environments include industrial machinery, HVAC blower assemblies, pump shafts, and conveyor drive components where stainless hardware is specified for corrosion resistance or food-grade compliance. The 3/8-16 UNC thread size is a standard coarse-thread series, compatible with widely available taps and threaded inserts.

Key Features

• Half dog point tip seats into a drilled locating hole for positive shaft positioning
• Austenitic grade A2 stainless steel construction resists corrosion in wet and chemical environments
• 3/8-16 UNC coarse-thread series for broad tooling and hardware compatibility
• 3/16 inch hex drive accepts standard hex keys and hex-bit drivers
• 1 inch overall length suits medium-depth threaded bores in collars and hubs
• Meets ASME/ANSI B18.3 and ASTM F880 dimensional and material standards

Compatibility

Designed as a standard-dimension replacement or new-installation set screw for any 3/8-16 UNC threaded bore requiring a half dog point fastener per ASME/ANSI B18.3 and ASTM F880.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 3/16 inch hex key or hex-bit driver. De-energize and lock out all rotating or pressurized equipment before removing or installing set screws per applicable OSHA lockout/tagout procedures. Apply appropriate thread-locking compound or anti-seize per the equipment manufacturer's specification when operating in high-vibration environments. Do not exceed the rated drive torque for the fastener size, and verify thread engagement depth before returning equipment to service.
